[TMBSED][Cl]2 was identified by 1H and 13C NMR, mass and FT-IR spectra. Then, its catalytic activity was examined to promote the following multicomponent reactions: (i) the production of 4,4´-(arylmethylene)-bis(3-methyl-1-phenyl-1H-pyrazol-5-ol)s from arylaldehydes and 3-methyl-1-phenyl-1H-pyrazol-5(4H)-one in ethanol, and (ii) the synthesis of 12-aryl-8,9,10,12-tetrahydrobenzo[a]xanthen-11-ones from arylaldehydes, dimedone and 2-naphthol in solvent-free conditions. The ionic liquid was highly efficient and general catalyst for these reactions.}, number={3}, journal={Iranian Journal of Catalysis}, publisher={OICC Press}, author={Zare, Abdolkarim and Sharif, Elaheh and Arghoon, Azam and Ghasemi, Marzieh and Dehghani, Bentolhoda and Ahmad-Zadeh, Sorayya and Zarei, Fatemeh}, year={2024}, month={Feb.}, keywords={12-Aryl-8, Acidic ionic liquid, [TMBSED][Cl]2, 4´-(Arylmethylene)-bis(3-methyl-1-phenyl-1H-pyrazol-5-ol), 12-tetrahydrobenzo[a]xanthen-11-one} }
